WebMultiple linear regression models can be implemented in Python using the statsmodels function OLS.from_formula () and adding each additional predictor to the formula … Web04. jul 2024. · The modelling application of OLS linear regression allows one to predict the value of the response variable for varying inputs of the predictor variable given the slope and intercept coefficients of the line of best fit. The line of best fit is calculated in R using the lm() function which outputs the slope and intercept coefficients.
